2 Claims.

This-invention relates to a smoking pipe and has for the primary object, the provision of a pipe which from-outward'appearance will be of a conventional construction; ,durable and light in weightandis-so constructed thatit will be selfcleaning, clogless; sogless, wasteless (and cool smoking.

"Another object of this invention is the provision ofxmeans'remoyably confined within the bore of the. pipe toprevent the passing of particles of tobacco, tobacco juiceand' saliva into the mouth ofthe smoker and.which will provide a medium for removing from'the bore the collected matter, permitting the pipeto be easilykept in a clean and sanitary condition.

Another object of this invention is the provision of a stem bore extending under the pipebowl on which feature in construction the above mentioned virtues depend ina large measure for practicability and effectiveness.

With these and other objects in view this inventionconsistsin certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a top planview illustrating a pipe constructed in accordance with my invention.

Figure .2 -is a sectional-view taken on the line 2--2 of Figure 1.

Figure 3 is a side elevation partly in section illustrating the combined cleaning element and medium for forming communicative chambers within the bore of the pipe.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

Figure 5 is a fragmentary sectional view illustrating the bowl and stem of the pipe with chambers formed in the bore by the cleaning medium.

Figure6 is a fragmentary sectional view illustrating the bit of the stem with a portion of the cleaning element mounted therein and showing a slight modification in construction from that disclosed in Figure 2.

Figure 7 isa detail view partly in section illustrating the connection between the cleaning element and the connecting ferrule employed between the bit and the stem of the pipe.

Figure 8 is a sectional view taken on a plane passing vertically through the cleaning element and ferrule showing the connection between said parts. 55 Referring in detail to the drawing, the numeral ter.

l indicates a smoking-pipeconsisting of a-bowl; 2 having an integral stem 3 and a removable bit 4. The stem 3 and bit 4 are provided with bores 5 that may be of substantially the same diame- Ihe bore of the bit has shown in Figure 2, may be reduced to a restricted passage 6 within the mouth piece of the bit so as to-provide in the bore of the bit a seat or shoulder 1. Thebore 5 of the stem 3 extendsunder the bowl 2 andis in communication with the interior of the bowl 101: 2 by openings 8 and the bore 5 of the stem may open outwardly through the heel of the bowl, as shown in Figure 2, or the bore may terminate within the heel of the bowl, as shown in Figure 5 Confined within the bore 5-of the stem and bit 15f? is a shaft 9 carrying at its ends heads lll,-one of which closes the bore 5 of the stem 3 where said bore opens outwardly through the heel of the bowl 2 and the other head engages theshoulder or seat 1. Integral withthe shaft 9 is 39, collar l I which engages thewalls of the'bore of thestem 3 preferably adjacent 'tothe bowlzfor forming a collecting chambernlland a condensing and cooling chamber l3. 'Thecondensingand cooling chamber l3 extends into the bit by; the bore of the latter. The shaft 9 is provided with a passage PM havingpreferably angularly related ends which open ,outwardly through opposite sides of the shaft and at ,opposite sides of the collar for the; purpose of establish- 0:. ing communication betweenythe, chambers 12 and is; The passage I4 is preferablyarranged so that one of its angularly related ends is located in close proximity to one face of the collar H and within the collecting chamber 12 and 35 directed downwardly when the pipe is positioned, as shown in Figure 2, or in an upright horizontal position, while the opposite end of the passage It opens into the chamber I3 through the top face of the shaft when the pipe is positioned, as 40 shown in Figure 2, and at a distance from the collar II. The passage. permits the smoke from the burning tobacco to pass from the collecting chamber I2 into the condensing and cooling chamber and due to its formation retards the 45 passing of particles of tobacco along with the smoke from the collecting chamber into the condensing and cooling chamber. The smoke when entering the condensing and cooling chamber contains a certain amount of moisture and tobacco juice which will readily settle and collect within the condensing and cooling chamber.

The shaft 9 is provided with a passage I5 openthe formation of the latter this saliva will be greatly hindered in returning to the mouth of the smoker and also should the pipe be tilted with the bit positioned lower than the bowl the collected saliva and condensedmoisture within the condensing and cooling chamber will be prevented from passing into the reduced passage 6 of the bit by the angularly related end of the passage l 5. Should the pipe be tilted in an opposite direction, that is, with the bowl in a slightly lowered position relative to the bit, the collected saliva within the condensing and cooling chamber will be prevented from passing into the collecting chamber 12 due to the formation of the passage M.

The shaft 9 may be Withdrawn from the bores 5 of the stem and bit when said stem and bit are detached .and the heads i0 and collar II will remove from said bores all foreign matter which may have collected therein.

The opposing ends of the stem and bit are preferably reduced and have formed thereon screw threads Hi to mesh with screw threads I! ofa connecting ferrule l8. The screw threads of the stem extend in an opposite direction to the screw threads of the bit and the screw threads open outwardly at the ends of the reduced portions'of the stem and bit and where said threads open outwardly, the ends of the reduced portions arenotched, as shown at l8, one wall of each notch aligning with a wall of the respective screw thread. The ends .of the reduced portions are also notched likewise but invertedly at their opposite sides from the notches I8. The notches receive therein substantially triangular shaped elements l9 carried by oppositely extending pins or projections 20 on the shaft 9 when the bit and stem are connected by the ferrule l8. The elements l9 are integral with the ferrule thereby connecting said ferrule to the shaft. The notches permit the reduced portions of the stem and bit mouth piece while the opposite end opens out- 7 to come into abutting engagement when connected by the ferrule l8 due to the triangular shaped elements fitting within said notches; also,

.by virtue of this arrangement either bit or stem can be removed one at a time at will and by choice from the ferrule and the cleaning shaft will remain firmly fixed in position in the one not removed.

Asshown in Figure 6, the bore of the bit may be of the same diameter throughout the length of the bit and when constructed in this manner the head at one end of the shaft frictionally contacts with the walls of the bore where the bore opens outwardly through the end of the bit engageable with the mouth of the user.

Having described the invention, I claim:

1. A smoking pipe comprising a bowl, a stem for said bowl and having a bore extending under said bowl, a bit for said stem and having a bore,

a ferrule detachably connecting the bit and stem, 0

a shaft connected to the ferrule and located in the bores, heads on the shaft to engage the walls of the bores, and a collar on the shaft to engage the walls of the bore of the stem and cooperate with the heads in forming chambers, said shaft having passages, one of said passages communicating with the chambers and the other passage communicating with one chamber and the bore of the bit and having .an angularly related end opening outwardly through a wall of the shaft, one of said passages having oppositely extending angularly related ends opening outwardly through opposite walls of the shaft with one angularly related end in one chamber and the other angularly related end in the other chamber.

2. A smoking pipe comprising a bowl, a stem for said bowl and having a bore extending under said bowl, a bit for said stem and having a bore, screw threaded extensions on said bit and stem, a screw threaded ferrule for connecting the screw threaded extensions, said extensions having oppcsitely arranged notches and certain of said notches having walls thereof aligning with walls of the threads of the extensions where said threads open outwardly through the ends of the extensions, a combined chamber forming medium and a cleaner confined in the bores of the stem and bit, and enlargements formed integrally within the ferrule and received within the notches and connected to said medium.
